Fair value as of: Jul 22, 2026
From 1 valuation models · updated 19 days ago
Share price +47.5% over the past month.
Below-average quality, and screening another 51% overvalued on our models.
What matters now
- The price sits above even our optimistic bull case (550.76 KRW). The favourable scenario is already priced in.
- The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
- Solid but not exceptional quality (48/100) and above fair value, neither a clear bargain nor a standout compounder.
- A fairly wide model range (290.80 KRW to 550.76 KRW) leaves room in how you read the outcome.

Analysis
ESTaid Corp (239340) currently trades at 894.00 KRW, while our model-based Fair Value estimate is 440.60 KRW, implying the stock looks roughly 50.7% overvalued today. The Quality Score stands at 48/100 (below-average quality), in the Communication Services sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: low).
Over the trailing twelve months, ESTaid Corp generated revenue of 14.9B KRW at a net margin of -43.3%. Revenue declined 15.1% year over year. It earns a return on equity of -38.1%. Fundamentals as of Jul 22, 2026
Our scenario range runs from 290.80 KRW (bear case) to 550.76 KRW (bull case); at 894.00 KRW, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 68% below its 52-week high and 17% above its 52-week low, currently below its 200-day average. For context, the median of 10 Communication Services peers we cover trades at 2% fair-value upside, at -51%, 239340 screens richer than that median.
Fair Value models
Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.
